I Patented Feb. 10, 1 931 UNITED STATEe PATENT OFFICE HENRY a-wrsn woon, or new YORK, a.

xgassienoit To WOOD NEWSPAPER Ma CHINERY CORPORATION, onivnw YonK,'1\T-.. Y., A cORrOR-ATION or VIRGINIA FOLDING MACHINE Application filed March 22, 1928. Serial K652153909.

The principal objects of the invention are to provide means for receiving the longitudinal folded edge of a web coming from the former, to prevent the inis-aligning of the looseends of the papers on account of the greater thicknessat the folded edge; to provide the rolls or cylinders about which the web travels with grooves for receiving the folded edge so as to allow'it plenty of room and prevent its getting the papers out of place on account of this thickness; and to provide a collar located in advance of the,

folding couple with a fluted same purpose. 7

Other objects and advantages of the in vention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig 1 is an end View in section of a part of a folding mechanism to which this invention can be applied; and

Fig. 2 is a developed side view showing the edge for the application of this invention to several of the rotary members. I p

lVhen newspapers are folded over the nose of the former, the longitudinal folded edge is generally left slightly uncreased, due to the fact that the nipping rolls between which it is led cannot be adjusted too tightly as they are considerably accelerated in speed and, having a knurled surface, cannot be expected to pinch the paper too tightly. For this reason the folded edge of the paper is expanded and in going around the cylinders, has a tendency to inis-alignthe loose ends of the pages due to the greater thickness of the pa per alon the folded edge.

The invention is shown as applied to a folding couple comprising a folding cylinder oneendf This-groove is located so that the fold 14 will enter it and the loop at theedge will run along in this groove and thereby avoid the mis-alignment which this fold often causes otherwise.

I have shown these grooves 15 in both members 10 and 11 of the folding couple. and also in the yielding cylinder 12. It will be seen that on account ofproviding this space for receiving this folded edge, its additional thickness can cause no trouble,"particularly if it'is provided in allthe cylindersbelow the IfupCping rolls. It also acts as a'guide for this Although I have illustrated and described only one form of the inventionI am aware of taefact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as ex pressed in the claims.

Therefore, I do not wish to be limited in these respects but what I do claim is 1, A folding machine having a, folding couple, the two cylinders of which are pro ided with circumferential grooves near one end to receive the longitudinal folded edge of a folded web passing between them, for the purpose described.

. 2. A folding machine having a cylinder in position to engagethe web, said roller having a groove around its circumference near the end to receive and guidethe longitudinally folded edge of the web. I j

I. In a folding machine, the combination with a folding couple, of roller located in position to engage the web before it passes into the folding couple, the said roller having a groove around its-circumference near the end where it will receive the longitudinally folded edgeofthe web to prevent mis-alignment of the web.

In testimony whereof I have hereunto aflixed my signature.
